Botulinum toxin urethral sphincter injection resolves urinary retention after pubovaginal sling operation

The management of prolonged urinary retention following pubovaginal sling surgery typically involves transvaginal urethrolysis for anatomical urethral obstruction. Brubaker recently reported on urethral sphincter abnormalities as a cause of postoperative urinary retention following either Burch suspension or a pubovaginal sling procedure. We report a case of functional urethral obstruction and detrusor acontractility following pubovaginal sling surgery that was successfully treated by botulinum A toxin urethral sphincter injection.
